Quick answer: Create a custom refresh rate in your GPU software: NVIDIA Control Panel > Change resolution > Customize > Create Custom Resolution, or AMD Adrenalin > Display > Custom Resolutions. Raise the refresh in 5Hz steps, test each with the on-screen confirmation, then set the new rate in Windows Settings > Display > Advanced. Verify with a frame skipping test before calling it done.
Step 1 – Know your starting point
Check the current mode under Settings > System > Display > Advanced display. While there, confirm the monitor runs its native resolution and that you are on a DisplayPort or recent HDMI cable: bandwidth is the ceiling, and ancient HDMI cables are the most common reason an overclock fails at the first step.
Our pick for this guide: Cable Matters DisplayPort 1.4 Certified Cable
A certified DisplayPort cable gives you the bandwidth headroom a stable overclock depends on.
Step 2 – Create the custom refresh rate
- NVIDIA: Control Panel > Display > Change resolution > Customize > Create Custom Resolution. Keep resolution native, raise refresh from 60 to 65, click Test. If the image holds and you confirm, save it.
- AMD: Adrenalin > Settings > Display > Custom Resolutions > Create New, same procedure.
- Intel: Graphics Command Center > Display > Custom Resolutions.
Repeat in 5Hz steps until the screen blacks out or artifacts appear, then settle one step below the failure point.
Step 3 – Apply it in Windows
The custom mode only exists after you select it: Advanced display > Choose a refresh rate and pick your new number. A black screen here reverts by itself in 15 seconds, so nothing is ever stuck.
Step 4 – Test for frame skipping
Open the UFO test, run the frame skipping pattern, and photograph the screen with a longish exposure. Continuous blocks mean a real overclock; gaps mean the panel drops frames at this rate, so step back down. Also glance at text sharpness and colors: heavy overclocks can subtly degrade both.
When the honest answer is a new panel
Overclocking buys 10 to 15 extra hertz; a modern gaming monitor triples the number and adds adaptive sync, which also cures the tearing covered in our screen tearing guide. Current picks: best gaming monitors, best 27-inch 1440p monitors and the budget 27-inch options.
Frequently asked questions
Can overclocking damage my monitor?
The realistic risk is low: a panel pushed too far shows a black screen, artifacts or frame skipping, and reverting the setting fixes it. Windows falls back automatically after 15 seconds if you cannot confirm the new mode. Long-term running far beyond spec can shorten panel life, which is why modest steps and frame-skip testing matter.
How much can a 60Hz monitor be overclocked?
Most 60Hz panels reach 65 to 75Hz depending on the controller and the cable. The jump from 60 to 75Hz is a very noticeable 25% smoothness gain in cursor movement and scrolling. High-refresh gaming panels usually have little headroom left, since manufacturers already sell them near their limit.
What is frame skipping and how do I test for it?
A monitor can accept a refresh rate but silently drop every few frames, which is worse than the lower stable rate. Run the classic UFO frame skipping test at testufo dot com and photograph the screen with a slow shutter: an unbroken line of lit squares means every frame is drawn, gaps mean skipping, so go back down 5Hz.
Small steps, a frame skip test, and DisplayPort instead of old HDMI cables: free hertz where the panel allows it, and an instant revert where it does not.
